while refer same name,which it refer to

[zrwsmd]

i have two same function name AddNumbers in my different files,their formal parameter type is (INT,INT) and (STRING,INT)
i call this function AddNumbers at main.st .
it seems that it refer the first function with param(INT,INT),
but another function with formal parameter type (STRING,INT) seems didn't work well.so can langium support multi refer same name?

[cdietrich]

you would need to adjust the scoping to look into the actual argument (types) and based on that put the correct function into the scope

[zrwsmd]

so should i still need to i override DefaultScopeProvider&getScope?where should i write this steps you mentioned above

[cdietrich]

yes

[cdietrich]

how does your grammar for function calls look like

[zrwsmd]

StFunction:
'FUNCTION' name=Identifier ('(' (reqParams+=ReqParams (',')?)* ')')? ':' variable_type=Native_Type_Name
(((varInputs+=VarInput)|(varOutputs+=VarOutput)|(varLocals+=VarLocal))*
(statementList+=Statement_list_single) )*
'END_FUNCTION'
;

ReqParams:
param=Identifier ':' typeName=Native_Type_Name;

That's the grammar for function definitions. But Christian asked for the grammar rule you use to call those functions.
